Learn how to use the Paper Size Calculator calculator and its working principles
The calculator works by using the formula: Area = Width × Height. This formula is applied regardless of the unit of measurement selected, with appropriate conversions being made to display the result in the desired unit.
If you enter a width of 8.5 inches and a height of 11 inches, and select inches as the unit, the calculator will display the area as 93.5 square inches. If you select centimeters, it will convert the dimensions to centimeters (assuming 1 inch = 2.54 cm) and display the area in square centimeters.
